Bisphenol A, a common precursor molecule used in the preparation of some polymers, was investigated as a possible scaffold for the design and synthesis of small-molecule gelators. To this end, a small library of ten molecules was synthesized by appending differentn-alkyl chains and aromatic moietiesviathep-hydroxyl groups in a single step. Five of these served as excellent gelators of several polar solvents. All the gelators containedn-alkyl chains, while none of the aromatic moieties imparted the gelling ability to the molecules. The minimum gelation concentrations ranged between 1-3%, with the ether-linked gelators more efficient than the ester-linked ones. The gel-to-sol transition temperatures observed for these gels were in the range of 26-54 °C. Detailed characterizations of the gels for two representative gelators were carried out using techniques like FTIR, UV-vis absorption, scanning electron microscopy, rheology, powder XRD, and contact angle measurement. The gels showed good absorption profiles for two water-soluble dyes. Based on these results, we propose that ‘bisphenol A’ can be conveniently exploited as a versatile core gelating scaffold in the design of many other small-molecule gelators.

Under microwave irradiation a number of phenols react remarkably fast with a number of primary alkyl halides to give aromatic ethers.
Novel Synthesis of N,N-Diarylarylmethanamines from N-(Arylmethylene)arenamines and (Arylmethoxy)arenes

Various N,N-diarylarylmethanamines were synthesized by the reaction of N-(arylmethylene)arenamines with (arylmethoxy)arenes in dimethylformamide solution in the presence of a strong base as a catalyst which is obtained in situ by reacting metallic sodium with this solvent.In general, the reaction may be depicted as the reduction of the imine and addition, on the original imino nitrogen atom, of the aryl group (of the aryloxy moiety) of the ether and presumably oxidation of the arylmethoxy group of the ether to its corresponding aldehyde.Side reactions and a proposed reaction mechanism are discussed.
