Exceptionally long crystal formation from 4-(3-bromopropyloxy)salicylaldehyde. X-Ray crystallographic investigation
Abstract
Unusually long ( > 14 cm) crystalline needles grow from 4-(3-bromopropyloxy)salicylaldehyde 1 presumably as a consequence of Br⋯Br interactions; the powdered form of 1 shows one order of magnitude greater SHG activity realtive to urea.
