Polydimethylsiloxanes with Grafted Dibenzoylmethanatoboron Difluoride: Synthesis and Properties.

A method for the preparation of polydimethylsiloxanes with grafted methoxy-substituted dibenzoylmethanatoboron difluoride has been described. The structures of prepared polymers were confirmed using NMR, IR spectroscopy and gel permeation chromatography methods. Their thermal properties were investigated using thermal gravimetric analysis, differential scanning calorimetry and thermomechanical analysis.

Photoprocesses in Derivatives of 1,4- and 1,3-Diazadistyryldibenzenes.

Photoprocesses in 1,4-diazadistyrylbenzene () and 1,3-diazadistyrylbenzene derivative () diperchlorates in MeCN were studied by absorption, luminescence, and kinetic laser spectroscopies. For compound , -photoisomerization and intersystem crossing to a triplet state are observed. For compound , photoelectrocyclization is suggested.
