A Heteromeric Carboxylic Acid Based Single-Crystalline Crosslinked Organic Framework.

Rongran Liang, Jayanta Samanta, Baihao Shao, Mingshi Zhang, Richard J Staples, Albert D Chen, Miao Tang, Yuyang Wu, Ivan Aprahamian, Chenfeng Ke,

The development of large pore single-crystalline covalently linked organic frameworks is critical in revealing the detailed structure-property relationship with substrates. One emergent approach is to photo-crosslink hydrogen-bonded molecular crystals. Introducing complementary hydrogen-bonded carboxylic acid building blocks is promising to construct large pore networks, but these molecules often form interpenetrated networks ... Read more >>
