The present invention provides a novel macrocyclic prodrug compound of general Formula (I), a pharmaceutical composition comprising a compound of Formula (I), and a method for treating diseases mediated by HDAC enzymes by administering a compound of Formula (I), wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.7, R.sup.8, R.sup.9, R.sup.10, R.sup.11, A and Z are defined herein.

##STR00001##

An organic light-emitting device includes a condensed cyclic compound represented by Formula 1:

##STR00001##

The condensed cyclic compound has an electron withdrawing group (EWG) substituent and an electron donating group (EDG) substituent at suitable positions, and thus has a low ΔE.sub.ST and may be used as an effective thermally activated delayed fluorescence (TADF) light-emitting material.

Processes for preparing compounds of Formula (1) and Formula (2) are described, wherein X, Y, Z, R.sub.1-R.sub.7, L and n are defined herein. Intermediates useful in the preparation of the compounds of Formula (1) and Formula (2) are also described.
