Abstract The structural and photoluminescence (PL) properties of thin films of poly(3-hexylthophene) (P3HT) with molecular weights (MWs) of 3000 and 13,300 have been investigated. Although high MW P3HT always self-organizes into one packing structure

A method to determine the intersystem crossing rate $(k_{\mathrm{ISC}})$ in the thermally activated delayed fluorescence (TADF) emitters has been reconsidered and applied to two TADF emitters, i.e., 1, 2-bis(carbazol-9-yl)-4,5-dicyanobenzene (2CzPN)
