The present invention provides a new class of solids supports for synthesis of modified oligomers of nucleic acids, and nucleic acid probes that have a format expediently synthesized on the new supports. Exemplary solid supports include at least one quencher bound through a linker to the solid support. Various exemplary embodiments include a moiety that stabilizes a duplex, triplex or higher order aggregation (e.g., hybridization) of nucleic acids of which the oligomer of the invention is a component. Other components of the solid support include moieties that stabilize aggregations of nucleic acids, e.g., intercalators, minor groove binding moieties, bases modified with a stabilizing moiety (e.g., alkynyl moieties, and fluoroalkyl moieties), and conformational stabilizing moieties, such as those described in commonly owned U.S. Patent Application Publication No. 2007/0059752.

The present invention provides a family of dark quenchers, termed Black Hole Quenchers (BHQs), that are efficient quenchers of excited state energy but which are themselves substantially non-fluorescent. Also provided are methods of using the BHQs, probes incorporating the BHQs and methods of using the probes.
