These molecules offer broad absorption\/emission properties and structure\u2010dependent dynamics. In this study, we used femtosecond pump\u2010probe spectroscopy to investigate the photo\u2010initiated dynamics of thiophene linked DPP derivatives. The thio\u2010DPPs are further functionalised by different electrons withdrawing terminal groups, namely benzoxazole and thiophene dicyanide. The benzoxazole derivative is strongly emissive and directly relaxes directly to the ground state chloroform solution. Thiophene dicyanide derivative exhibits distinct spectral evolution in the first 10\u2005ps, associated with structural and vibronic process. Later, it crosses over to the triplet state with a yield of 20\u2009%. In the solid\u2010state (thin film), we observed a signal that resembles singlet fission. However, upon careful analysis of temperature\u2010dependent steady state absorbance spectra, we conclude that these features are due to laser\u2010induced thermal artifacts. We describe a simplified excited state evolution in the thin film that does not include any additional excited states. These findings have significant implications for the analysis of triplet formation, which plays a major role in the photophysics of many organic materials.<\/jats:p>","DOI":"10.1002\/cphc.202300872","type":"journal-article","created":{"date-parts":[[2024,4,4]],"date-time":"2024-04-04T08:29:30Z","timestamp":1712219370000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Photophysics
