说明

General description

2-硝基苯甲醛中的2-硝基苄基具有光不稳定性，当暴露于紫外光时会发生裂解。

Application

2-硝基苯甲醛可与壳聚糖反应形成2-硝基苄基-壳聚糖，其可溶于三氟乙酸，也可电纺成纳米纤维基质。在光解时，硝基苄基被裂解，以获得纯的壳聚糖纳米纤维基质。相同的原理已被应用于明胶纳米纤维基质的制备。o-NBA与2-氨基苯并噻唑的缩合反应可形成 o-硝基亚苄基-2-氨基苯并噻唑，其是一种Schiff碱，可与金属离子反应形成络合物。

Impact of vibrational excitation on the kinetics of a nascent ketene.

Thomas Schmierer et al.

Physical chemistry chemical physics : PCCP, 11(48), 11596-11607 (2009-12-22)

The formation and decay of a ketene intermediate photochemically formed from o-nitrobenzaldehyde has been studied by femtosecond UV/Vis and IR spectroscopy. The ketene is formed predominantly within a few 100 fs and to a minor extent within approximately 200 ps

A non-adiabatic quantum-classical dynamics study of the intramolecular excited state hydrogen transfer in ortho-nitrobenzaldehyde.

Physical chemistry chemical physics : PCCP, 13(32), 14685-14693 (2011-07-08)

Ab initio surface-hopping dynamics calculations have been performed to simulate the intramolecular excited state hydrogen transfer dynamics of ortho-nitrobenzaldehyde (o-NBA) in the gas phase from the electronic S(1) excited state. Upon UV excitation, the hydrogen is transferred from the aldehyde
