Lutetium thermal properties

Because of their electrical, optical, and redox properties as well as the thermal and chemical stability, the Pcs also have been tried in the detection of volatile organic compounds and poisonous gases, which is very important for environment and human health. In the past decades, the possible applications of Pc thin film as sensor for atmospheric gaseous pollutants have been extensively studied [73, 74], Langmuir-Blodgett films of some multinuclear and multidouble-decker lutetium Pcs have also been used for those measurements [75,76], More details about conductivity and sensing properties of Pcs can be found elsewhere [77,78]. 

The only class of lanthanidomesogens for which electrical properties have been investigated in detail, are the bis(phthalocyaninato)lanthanide(III) sandwich complexes. As already described in Section 8, the free electron in these complexes is associated with the extensive re-system of the phthalocyanine macrocycles. The individual Pc2Lu units can be considered nominally as Lu " Pc2 The bis(phthalocyaninato)lutetium(III) complexes are intrinsic molecular semiconductors. The generation of charge carriers can be represented by the reaction AAA A free carriers, where A is the molecular unit. The ionized pair A " A is photochemically or thermally activated.
