Nanocrystalline semiconductor oxides are obtained by chemical precipitation with subsequent thermal annealing and characterized by XRD, SEM and single-point BET methods. The heterocyclic Ru(II) complex is synthesized for the first time and investigated by 1H NMR, 13C NMR APT, MALDI-MS analysis, and UV-Vis spectroscopy. The HOMO and LUMO energies of the Ru(II) complex are calculated from cyclic voltammetry data. The hybrid materials are characterized by TGA-MS analysis and EDX mapping. The optical properties of hybrids are studied by UV-Vis spectroscopy in the diffuse reflection mode. The investigation of spectral dependencies of photoconductivity of hybrid samples demonstrates that the role of organic dye consists in shifting the photosensitivity range towards longer wavelengths. Sensor measurements demonstrate that hybrid materials are able to detect NO2 in the concentration range of 0.25\u20132 ppm without the use of thermal heating under periodic illumination with even low-energy long-wavelength (red) light.<\/jats:p>","DOI":"10.3390\/nano8090671","type":"journal-article","created":{"date-parts":[[2018,8,30]],"date-time":"2018-08-30T02:49:34Z","timestamp":1535597374000},"page":"671","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Photosensitive Organic-Inorganic Hybrid Materials for Room Temperature Gas Sensor Applications"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3354-0885","authenticated-orcid":false,"given":"Marina","family":"Rumyantseva","sequence":"first","affiliation":[{"name":"Chemistry Department, Moscow State University, 119991 Moscow, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5133-4009","authenticated-orcid":false,"given":"Abulkosim","family":"Nasriddinov","sequence":"additional","affiliation":[{"name":"Chemistry Department, Moscow State University, 119991 Moscow, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Svetlana","family":"Vladimirova","sequence":"additional","affiliation":[{"name":"Chemistry Department, Moscow State University, 119991 Moscow, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sergey","family":"Tokarev","sequence":"additional","affiliation":[{"name":"Chemistry Department, Moscow State University, 119991 Moscow, Russia"},{"name":"Nesmeyanov Institute of Organoelement Compounds of the Russian Academy of Sciences, 119991 Moscow, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Olga","family":"Fedorova","sequence":"additional","affiliation":[{"name":"Chemistry Department, Moscow State University, 119991 Moscow, Russia"},{"name":"Nesmeyanov Institute of Organoelement Compounds of the Russian Academy of Sciences, 119991 Moscow, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ivan","family":"Krylov","sequence":"additional","affiliation":[{"name":"Physics Department, Moscow State University, 119991 Moscow, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Konstantin","family":"Drozdov","sequence":"additional","affiliation":[{"name":"Physics Department, Moscow State University, 119991 Moscow, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2378-7446","authenticated-orcid":false,"given":"Alexander","family":"Baranchikov","sequence":"additional","affiliation":[{"name":"Chemistry Department, Moscow State University, 119991 Moscow, Russia"},{"name":"Kurnakov Institute of General and Inorganic Chemistry of the Russian Academy of Sciences, 119991 Moscow, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexander","family":"Gaskov","sequence":"additional","affiliation":[{"name":"Chemistry Department, Moscow State University, 119991 Moscow, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,8,29]]},"reference":[{"key":"ref_1","unstructured":"World Health Organization (2018, August 12).
