The present invention relates to hole-transport materials for organic solar cells or organic optical sensors. In particular the present invention relates to a compound of general formula (I)
wherein
A is a group which connects all L moieties by a π-conjugated system which is formed by olefinic groups, aromatic groups, heteroaromatic groups, sandwich groups, atoms with unbound electron pairs, or combinations thereof,
Z is hydrogen, an alkyl group, an aryl group, or a heteroaryl group,
R1, R2, R3, R4 are independent of each other alkyl groups, aryl groups, or heteroaryl groups,
n is an integer of at least 2.
