Abstract: A film, preparation method thereof and photoelectric device are disclosed. A material of the film includes an organic p-type semiconductor material and a dopant, and the dopant is selected from one or more of a polycyano conjugated compound and a polytrifluoromethyl conjugated compound. The film has high hole mobility.

Abstract: Disclosed in the present disclosure are a polymer, a composition, and an optoelectronic device. The polymer has a structure of formula (I), wherein n is any integer from 10 to 50, Ar1 is selected from any one of the following structures, Ar2 and Ar3 are each independently selected from any one or more of a substituted or unsubstituted aryl group having 6 to 14 ring atoms, and a substituted or unsubstituted heteroaryl group having 5 to 14 ring atoms.

Abstract: Disclosed herein are integrated preparation and detection devices for studying biomass-burning aerosols, where the devices include a micro-fluidized bed reactor (MFBR), a transmission line, and an on-line detection unit that are connected in sequence. The MFBR may include a pyrolysis reactor and a pyrolysis furnace; the pyrolysis reactor may include a thermocouple, an introduction tube, and quartz sands; the on-line detection unit may be an on-line photoionization mass spectrometer; and the photoionization mass spectrometer may include a laser desorption system, a laser ionizer and a light energy ionizer. Devices of the present disclosure are beneficial to retain the original state of aerosol particles, and the fixed MFBR can realize rapid pyrolysis of a biomass due to its high and stable heat conduction efficiency, which is beneficial to studying the formation mechanism of aerosol particles.
