This Letter reports some interesting results on twisted intramolecular char
ge transfer emission of 4-N,N-dimethylaminocinnamic acid complexed with alp
ha -cyclodextrin. Salient features of this investigation, as revealed from
twisted intramolecular charge transfer emission intensity and position depe
ndence on alpha -CD concentration, are the formation of 1:2 barrel-shaped c
omplex in addition to 1:1complex, while twisted intramolecular charge trans
fer (TICT) band intensity shows an increase and then a sharp decrease (bell
-shaped variation) along with blue shift and initial addition of base to th
e solution obstructs the formation of 1:2 complex. (C) 2001 Elsevier Scienc
