초록

where L' is a moiety which forms a stable radical with acceptor moiety A upon transfer of an electron from donor moiety D.sup.- to electron acceptor moiety A, and G is a moiety which forms a leaving group upon transfer of the electron from donor moiety D.sup.- to acceptor moiety A.

대표청구항 ▼

[ What is claimed is:] [1.] A compound of the formula EQU A-L.sup.+ D.sup.- re A is a moiety which absorbs radiation and enters an excited state in which it accepts an electron; L is a linking group which tethers an electron acceptor moiety A to the electron donor moiety D.sup.- ; and D.sup.- is a moiety represented by the formula (V): [ STR 23 ] where Z is an element selected from the group consisting of boron, aluminum and gallium and R.sup.8, R.sup.9, R.sup.10 and R.sup.11 are independently selected from the group consisting of alkyl, aryl, alkaryl, aralkyl, alkenyl, alkynyl, alicyclic, heterocyclic and a cyclic group wherein at least two of the R.sup.8, R.sup.9, R.sup.10 and R.sup.11 may combine to form a cyclic group, wherein said moiety D.sup.- donates an electron to the excited state of the A moiety and releases a free radical; and L.sup.+ is a cationic linking group of the formula EQU -L'-G- re L' is a moiety which forms a stable radical with the acceptor moiety A upon transfer of an electron from the donor moiety D.sup.- to the acceptor moiety A and G is moiety which forms a leaving group upon said transfer and is selected from the group consisting of ammonium, phosphonium, arsonium, antimonium, sulfonium, oxonomium, thioxonium, halonium and polyvalent metal cation.
