Crown-ether lutetium bisphthalocyanine Langmuir-Blodgett films as gas sensors

Characterisation of Langmuir–Blodgett films of new multinuclear copper and zinc phthalocyanines and their sensing properties to volatile organic vapours

“…It is well known that Langmuir-Blodgett technique makes it possible to prepare organic functional ultrathin films with a controlled thickness at a molecular level and with different molecular orientation. Hence LB films of several metallo-phthalocyanine derivatives such as monomers and planes for CuPc [10][11][12][13][14][15], CoPc [16], ZnPc [17][18], a monomer and not plane for PbPc [19][20][21], and a dimmer for LuPc [22] have been prepared and characterized in detail because of their activity for gas sensing applications.…”
