✦ Synopsis

Pressure effects on the twisted intramolecular charge transfer (TICT) phenomenon of 4-(N,Ndimethylamino)benzoate bonded to a polymer side chain (copDB) and its low molecular weight model compound (DBAE) were examined in ethyl acetate. The volume change and the activation volume for the formation of the TICT state were determined to be 2.9 cm3/mol (DBAE) and 5.5 cm'/mol (copDB), respectively. Although the present results for copDB are reasonably explicable as the viscosity effect on the TICT state formation, the effect could not be described by the normal Stokes-Einstein theory but required the Gierer-Wirtz theory.

It is shown that the relative intensity of the twisted intramolecular charge transfer band of ester and benzonitrile derivatives of dialkylanibne in non-hydrogen-bonding polymers increases with increasing size of the donor (dialkylamino) group and is sensitive to both the local polarity and local fr
