New, neutral, meso-substituted tetraoxa[22]annulene[2,1,2,1] aromatic macrocycles are synthesised and disclosed as new p-type semiconductors with reproducible bulk-like carrier mobility (as high as 0.40 cm(2) V(-1) s(-1)) on highly crystalline thin films deposited on octadecyltrichlorosilane modified SiO(2).
