Kurzfassung:
Reactions of the N,C,N-chelated organogallium amide LGa(NEt 2 ) 2 (1), where L is {2,6-(Me 2 NCH 2 ) 2 C 6 H 3 } − , with organoboronic acids RB(OH) 2 yielded molecular gallium boroxines LGa(O 3 B 2 R 2 ) (2: R = OH, 3: R = Ph, 4: R = 4-MeO–C 6 H 4 , 5: R = 4-CHO–C 6 H 4 , 6: R = Fc), neutral analogues of gallaborates. The molecular structures revealed the presence of a six-membered central GaB 2 O 3 ring. The film forming properties of 5 allowed the deposition of transparent thin films by a spin coating method. The thicknesses, refractive index, energy of the optical gap ( E optg), activation energy of surface electrical conductivity ( E sa) and pre-exponential factor ( σ 0 ) of the thin layers of 5 were measured and they are close to those found for related oxygen glass. Finally, GBO 5 was also used as an additive to printing ink and a thin film of 5 was prepared by the gravure printing technique.
