Sub-classes:

C09K19/12 » at least two benzene rings directly linked, e.g. biphenyls 487
C09K19/14 » linked by a carbon chain 118
C09K19/20 » linked by a chain containing carbon and oxygen atoms as chain links, e.g. esters {or ethers} 345
C09K19/22 » linked by a chain containing carbon and nitrogen atoms as chain links, e.g. Schiff bases 62
C09K19/24 » linked by a chain containing nitrogen-to-nitrogen bonds 76
C09K19/28 » linked by a chain containing carbon and sulfur atoms as chain links, e.g. thioesters 20
