The preparation of polynuclear compounds containing the thiophene ring system
The process of C. K. Bradsher for preparing mesosubstituted anthracene and 1,2-benzanthracene derivatives has been widely extended. The purpose of this research was to extend this process to the thiophene series, in addition to continuing some work on the 9-(dimethyl)- phenylanthracene series and …

Squaric acid as a versatile compound in the design of molecular solids
… or a hydrogen-bonding motif, three classes of compounds have been synthesized and characterized by single-crystal X-ray diffraction: 1. Hydrogen-bonded systems based on acid-base reactions of biguanide derivatives (N,N-dimethylbiguanide, N-phenylbiguanide, N-o-tolylbiguanide) and squaric acid. …
