Herein, these effects are investigated in bichromophoric systems where two 1,4-bis(phenylethynyl)benzene chromophores are arranged obliquely on RR- and SS-1,2-cyclohexanediamine scaffolds. The interaction is progressively detuned by varying the transition energy of one chromophore through substitution with diphenylacetylene or phenyl units, while retaining the other chromophore as 1,4-bis(phenylethynyl)benzene. The CD band shape evolves from bisignate to monosignate as exciton coupling changes from degenerate to quasi-degenerate and nondegenerate, since one of the CD peaks undergoes a hypsochromic shift and eventually leaves the spectral window of interest, concomitant with a decrease in gabs. All bichromophoric systems exhibit similar emission spectra, quantum yields, and lifetimes, whereas glum decreases upon detuning, indicating that CPL originates from 1,4-bis(phenylethynyl)benzene due to the chiral electrostatic environment imposed by the neighboring chromophore.<\/jats:p>","DOI":"10.1021\/acs.jpclett.6c02333","type":"journal-article","created":{"date-parts":[[2026,8,19]],"date-time":"2026-08-19T08:02:27Z","timestamp":1787126547000},"page":"9892-9901","source":"Crossref","is-referenced-by-count":0,"title":["Bichromophores\nas a Molecular Platform to Explore\nChiroptical Responses: Resonant Coupling and Beyond"],"prefix":"10.1021","volume":"17","author":[{"given":"Edakkandiyil","family":"Aiswarya","sequence":"first","affiliation":[{"name":"Indian Institute of Science Education and Research Thiruvananthapuram (IISER TVM) , , Vithura , ,","place":["Thiruvananthapuram, India, 695 551"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-3651-8241","authenticated-orcid":true,"given":"Matteo","family":"Bedogni","sequence":"additional","affiliation":[{"name":"Universita\u0300 di Parma , , Parco Area delle Scienze 17A , ,","place":["Parma, Italy, 43124"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meleppatt","family":"Sujith","sequence":"additional","affiliation":[{"name":"Indian Institute of Science Education and Research Thiruvananthapuram (IISER TVM) , , Vithura , ,","place":["Thiruvananthapuram, India, 695 551"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-5059-5382","authenticated-orcid":true,"given":"Joel J.","family":"Parakadavil","sequence":"additional","affiliation":[{"name":"Indian Institute of Science Education and Research Thiruvananthapuram (IISER TVM) , , Vithura , ,","place":["Thiruvananthapuram, India, 695 551"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1972-1281","authenticated-orcid":true,"given":"Cristina","family":"Sissa","sequence":"additional","affiliation":[{"name":"Universita\u0300 di Parma , , Parco Area delle Scienze 17A , ,","place":["Parma, Italy, 43124"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3500-3848","authenticated-orcid":true,"given":"Anna","family":"Painelli","sequence":"additional","affiliation":[{"name":"Universita\u0300 di Parma , , Parco Area delle Scienze 17A , ,","place":["Parma, Italy, 43124"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1279-308X","authenticated-orcid":true,"given":"K.
