The ratio of A2/A1 corresponds to the relative activity of adsorbates at site 2 relative to site 1, while 2/1 corresponds to timescale associated with the adsorption rate at site 2 relative to the adsorption rate at site 1. The sharp increase in M which occurs for P/P0<0.4 (Fig. Molecular Crystals and Liquid Crystals Humidity effect on gravimetric properties., Humidity effect on gravimetric properties. The applications of CuTCPc as donor and interlayer materials in solar cell devices are investigated. CuPc (copper phthalocyanine) was first prepared in 1927 by the reaction of copper(I) cyanide and o-dibromobenzene, which mainly produces colorless phthalonitrile as well as an intensely blue by-product. Thank you for visiting nature.com. Application QCM frequency shift was recorded using an SRS QCM200 and direct-current (DC) electrical resistance was recorded using a Keithley 2420 source-meter with 100mV bias.
