Ss. Mandal et al., EXCEPTIONALLY LONG CRYSTAL-FORMATION FROM 4-(3-BROMOPROPYLOXY)SALICYLALDEHYDE - X-RAY CRYSTALLOGRAPHIC INVESTIGATION, Chemical communications, (24), 1996, pp. 2725-2726
Unusually long (>14 cm) crystalline needles grow from 4-(3-bromopropyl
oxy)salicylaldehyde 1 presumably as a consequence of Br ... Br interac
tions; the powdered form of 1 shows one order of magnitude greater SHG
activity realtive to urea.
