Provided is a highly efficient method for the production of aldehydes and ketones, which is inexpensive, exhibits high reactivity, and is capable of easy separation of byproduct after the reaction. More particularly, there is provided a method for producing an aldehyde or a ketone, comprising at least an oxidation step of oxidizing a primary alcohol or a secondary alcohol in the presence of a polymeric carbodiimide represented by the following formula (1) and having a weight-average molecular weight of 300 to 5000, and a sulfoxide compound, together with an acid and a base, or together with a salt of the acid and the base.

The present invention is a fluorescent probe for detecting chemicals, particularly chemical warfare agents. The probe has a novel selection of polymers and fluorophores that allow for laser excitation and photodiode detection of chemical warfare agents. A probe based on poly(epichlorohydrin) as the polymer and nile blue A perchlorate as the fluorophore is sensitive to concentrations of mustard of less than 30 ppb. Probes based on fluoropolyol as the polymer and oxazine 170 perchlorate as the fluorophore is sensitive to low concentrations of soman. Selecting a cationic fluorophore that has an affinity for the chemical agent of interest and immobilizing that fluorophore in a polymer matrix provides a fluorescent probe capable of detecting the presence of the desired chemical agent in trace quantities. A set of probes may be used so that in the presence of an analyte or a mix of analytes one or more of the probes may be responsive.
本发明是一种用于检测化学品,特别是化学战剂的荧光探针。该探针采用了新颖的聚合物和荧光团,可通过激光激发和光电二极管检测化学战剂。以聚环氧氯丙烷为聚合物、尼罗蓝 A 高氯酸盐为荧光团的探针对浓度低于 30 ppb 的芥子气非常敏感。以含氟多元醇为聚合物、恶嗪 170 高氯酸盐为荧光体的探针对低浓度的索曼敏感。选择一种与所需化学制剂有亲和力的阳离子荧光团,并将该荧光团固定在聚合物基体中,就能得到一种能检测痕量所需化学制剂的荧光探针。可以使用一组探针,这样在分析物或分析物混合存在的情况下,其中一个或多个探针可以做出反应。
