Abstract
In the present work, we successfully synthesised a series of phthalocyanine complexes with varying the number and nature of halogens (F0, F8, F16 and Cl8) and the metal centre (Co, VO, Zn and Cu). By engaging these molecules as a sublayer, we fabricated bilayer heterojunction sensors with LuPc2 as a top layer and investigated their sensing properties towards both oxidizing and reducing gaseous spe-cies (NH3, NO2 and O3). The resulting heterojunction devices exhibit p-type, n-type or ambipolar (both p- and n-type) behaviours, depending on an external trigger.
