Abstract: Air sampling sensor and system for detecting volatile organic compounds and applications thereof. A nanoparticle-structured chemiresistive sensor array in the analyzer generates an output signal based on the presence of selected volatile organic compounds in an air sample. The sensors of the array include sensing films from the group of molecularly-linked gold nanoparticles with different linking and capping molecules and gold nanoparticles of different sizes. A micro-processing unit analyzes the output signal of the sensor array and indicates the presence or absence of selected volatile organic compounds. The air sampling system can be used to analyze human breath and report the presence of volatile organic compounds relevant to lung cancer biomarkers. The air sampling system can also be used as an environmental air monitoring system to detect the presence of hazardous chemicals in the air.

Abstract: Provided are a nitrogen-containing compound, an organic electroluminescent device and an electronic apparatus. The nitrogen-containing compound has a structure as shown in chemical formula 1; Ar1 and Ar2 are the same or different, and each is independently selected from a substituted or unsubstituted C6-C30 aryl, or a substituted or unsubstituted C3-C30 heteroaryl; and R0 is selected from hydrogen, a C1-C6 alkyl, a substituted or unsubstituted C6-C30 aryl, or a substituted or unsubstituted C3-C30 heteroaryl. The nitrogen-containing compound acts as a hole transporting material or a host material of a luminescent layer and can effectively improve the performance of organic electroluminescent devices.
