Heteroaromatic-conjugated aromatic molecules have inspired numerous interests in rechargeable batteries like Li-ion batteries, but were limited by low conductivity and easy dissolution in electrolytes. Herein, we immobilize a nitrogen-rich aromatic molecule tricycloquinazoline (TQ) and CuO4 unit into a two-dimensional (2D) conductive metal–organic framework (MOF) to unlock their potential for Li+ storage. TQ was identified redox activity with Li+ for the first time. With a synergistic effect of TQ and CuO4 unit, the 2D conductive MOF, named Cu-HHTQ (HHTQ=2,3,7,8,12,13-hexahydroxytricycloquinazoline), can facilitate the Li+/e? transport and ensure a resilient electrode, resulting in a high capacity of 657.6 mAh g?1 at 600 mA g?1 with extraordinary high-rate capability and impressive cyclability. Our findings highlight an efficient strategy of constructing electrode materials for energy storage with combining multiple redox-active moieties into conductive MOFs.

The development of different classes of porous polymers by linking organic molecules using new chemistries still remains a great challenge. Herein, we introduce for the first time the synthesis of covalent quinazoline networks (CQNs) using an ionothermal

The preparation of N-phenylbenzamidine 3a from the reaction between benzonitrile Ia and aniline in the presence of AId3 is reinvestigated with respect to mode of reagent addition, reaction temperature and Lewis acid catalysis. Pre-forming the nitrile-Lewis acid complex prior to the addition of aniline allows for milder reaction conditions, allowing for the higher yielding synthesis of N-phenylbenzamidine 3a (83%). Using these modified conditions several N-(4-substituted phenyl)benzamidines can be prepared including the N-(4-methoxyphenyl)benzamidine 3b (93%) and the previously unobtainable 2-amino-N-(4-methoxyphenyl)benzamidine 31(56%). All new compounds are fully characterised.

2,3-Dihydro-1-benzyl-2,2-disubstituted-4(1H)-quinazolinones (II, R=Ph), obtained by the condensation of o-benzylaminobenzamide (I, R=Ph) with ketones in acetic acid, on pyrolysis yield 2-phenyl-4(3H)-quinazolinone (III, R=Ph). o-Aminobenzamides, on pyrolysis however give different types of products depending on the nature of substituents.
