1. A compound having the structure (1):
- ##STR38## and tautomers, solvates and salts thereof, wherein R1 is an oligonucleotide, a protecting group, a linker or --H;
R2 is A(Z)X1, wherein A is a spacer and Z independently is a label bonding group optionally bonded to a detectable label, but R2 is not amine, protected amine, nitro or cyano;
R27 is independently --CH═
, --N═
, --C(C1 -C8 alkyl)═
or --C(halogen)═
, but no adjacent R27 are both --N═
, or two adjacent R27 are taken together to form a ring having the structure, ##STR39## where Ra is independently --CH═
, --N═
, --C(C1-8 alkyl)═
or --C(halogen)═
, but no adjacent Ra are both --N═
;
R34 is --O--, --S-- or --N(CH3)--; and
