Understanding the phase formation and degradation behavior of these materials is crucial towards their use in optoelectronic devices, since different crystal phases possess different optical and electronic properties. In this communication, we study the phase formation and degradation of a series of hybrids containing bithiophene, terthiophene and quaterthiophene derivatives. We show that two crystal phases can be formed for each of these systems, depending on the processing conditions. One phase corresponds to a 2D layered perovskite and the other phase has optical properties corresponding to a dimensionality intermediate between a 2D and a 1D hybrid. | Keywords: | low-dimensional;organic-inorganic hybrid composites;perovskite phases;stability;oligothiophenes | Document URI: | http://hdl.handle.net/1942/36149 | ISSN: | 2199-692X | e-ISSN: | 2199-692X | DOI: | 10.1002/cnma.202100169 | ISI #: | 000663164100001 | Rights: | 2021 Wiley-VCH GmbH | Category: | A1 | Type: | Journal Contribution | Validations: | ecoom 2022 |
