Amphiphilic mixed (phthalocyaninato)(porphyrinato)europium(III) triple‐decker complexes Eu 2 [Pc(15C5) 4 ] 2 [T(C 10 H 21 ) 4 P] ( 1 ) and Eu 2 [Pc(15C5) 4 ] 2 [TPOPP] ( 2 ) [H 2 Pc(15C5) 4 = 2,3,9,10,16,17,23,24‐tetrakis(15‐crown‐5)phthalocyanine; H 2 T(C 10 H 21 ) 4 P = meso ‐5,10,15,20‐tetra‐ n ‐decylporphyrin, H 2 TPOPP = meso ‐5,10,15,20‐tetrakis(4‐pentyloxyphenyl)porphyrin] were designed and synthesized by the raise‐by‐one‐story method. These novel sandwich triple‐decker complexes were characterized by a wide range of spectroscopic methods, and they were also electrochemically studied. Highly ordered films were fabricated by the Langmuir–Blodgett (LB) technique into organic field‐effect transistors (OFETs). The devices display good OFET performance with a carrier mobility in the range 0.03–0.78 cm 2 V –1 s –1 . As expected, the devices show a low threshold voltage range from –1.19 to –4.34 V. The mobility of compound 1 reaches 0.78 cm 2 V –1 s –1 , which is the highest value so far achieved for LB film‐based OFETs, as a result of the narrow energy gap (1.04 eV) of this compound.(© Wiley‐VCH Verlag GmbH & Co.
