Their unique properties have led the chemical community, since the earliest\nstudies, to embrace the challenge of synthesizing porphyrins. In the quest to produce and\nmanipulate the periphery of these macrocyclic systems for more useful and versatile applications,\nvarious strategies have been implemented. Among these, the synthesis of macromolecular systems\nbased on covalently linked porphyrins is one of the most interesting. It is generally believed\nfrom the large number of studies conducted that inter-porphyrin interactions occur when there is a\nstrong overlap of the macrocyclic  orbitals mediated by the linkage. While nature uses diverse covalent linkages and self-assembled interactions,\nour mastery of these is still in its infancy. Attempts to imitate and explore nature sometimes provide chemists with a fertile\nfield for synthetic and mechanistic studies. Synthetic bis-porphyrin prepared for a wide variety of purposes have generally utilized covalent\nlinkers to maintain desired geometry and to control the electronic communication between the two porphyrin moieties involved. This\nreview aims to highlight recent synthetic strategies and the various routes employed to design and synthesize these macrocyclic systems\nas free-base or metallated forms, with linkages of varied nature, to fine tune the overall system properties for particular applications. Because\nof the extent of this subject in terms of macromolecular porphyrin systems, in this review we have focused only on bis-porphyrin\nsystems, and have ignored coverage of macromolecular and supramolecular porphyrin based systems that involve more than two porphyrin\ncores.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.2174\/1385272819666150113001536","type":"journal-article","created":{"date-parts":[[2015,1,14]],"date-time":"2015-01-14T14:20:47Z","timestamp":1421245247000},"page":"599-651","update-policy":"https:\/\/doi.org\/10.2174\/bsp_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Covalently Linked Free-Base and Metallo-Bis-Porphyrins: Chemistry and Diversity"],"prefix":"10.2174","volume":"19","author":[{"given":"Mohmmad","family":"Younus Wani","sequence":"first","affiliation":[{"name":",0"}]},{"given":"Avula","family":"Balakrishna","sequence":"additional","affiliation":[{"name":",0"}]},{"given":"Santosh","family":"Kumar","sequence":"additional","affiliation":[{"name":",0"}]},{"given":"Abilio","family":"J.F.N Sobral","sequence":"additional","affiliation":[{"name":"Departamento de Qu mica, Universidade de Coimbra, Rua Larga, Coimbra,3004-535, Portugal.,Portugal"}]}],"member":"965","container-title":["Current Organic Chemistry"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.eurekaselect.com\/article\/download?doi=10.2174\/1385272819666150113001536","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.eurekaselect.com\/127580\/article","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.eurekaselect.com\/article\/download?doi=10.2174\/1385272819666150113001536","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,25]],"date-time":"2025-10-25T12:57:50Z","timestamp":1761397070000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.eurekaselect.com\/127580\/article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,4]]},"references-count":0,"journal-issue":{"issue":"7","published-print":{"date-parts":[[2015,4]]}},"alternative-id":["LiveAll1"],"URL":"https:\/\/doi.org\/10.2174\/1385272819666150113001536","relation":{},"ISSN":["1385-2728"],"issn-type":[{"type":"print","value":"1385-2728"}],"subject":[],"published":{"date-parts":[[2015,4]]},"assertion":[{"value":"Peer Reviewed","order":0,"name":"review_status","label":"Review Status","group":{"name":"peer_review_details","label":"Peer Review Details"}},{"value":"Double blind","order":1,"name":"review_process","label":"Review Process","group":{"name":"peer_review_details","label":"Peer Review Details"}},{"value":"Checked with iThenticate","order":0,"name":"screening_status","label":"Screening Status","group":{"name":"plagiarism_screening","label":"Plagiarism Screening"}},{"value":"2014-06-14","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2015-01-08","order":1,"name":"revised","label":"Revised","group":{"name":"publication_history","label":"Publication History"}},{"value":"2015-01-12","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2015-05-06","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
