Abstract
The effect of temperature (from 296 to 423 K) upon the absorption and fluorescence of 1-phenyl-4-diphenylthiophosphinyl butadiene (PDPB) and of the direct irradiation on the absorbance were investigated in poly (vinyl alcohol) film. It was found that for PDPB in PVA film the trans ition from cis to trans configuration is only possible as a result of thermal isomerization due to the softening of PVA polymer, whereas pho toisomerization results in both cis-to-trans and trans-to-cis transiti ons. Similar as with 1,4-diphenyl-1,3-butadiene in PVA, the luminescen ce is due to two, trans-trans and cis-trans, PDPB conformers.
