Konstantinos 232 was the son of the emperor Theophilos 5; he was buried, like his father Theophilos 5 and his sister Maria 4, in the Mausoleum of Justinian at the Church of the Holy Apostles (ἕτερον λαρνάκιον πράσινον, ἐν ᾧ ἀποκεῖται Κωνσταντῖνος, ὁ υἱὸς Θεοφίλου): Const. Porph., De Cer. II 42 (Reiske, 645). He is named on imperial seals of his father, but has apparently disappeared from seals of the second indiction, in 832/833, and he may have already been dead by then; see Zacos and Veglery 285 and cf. Hunger, BZ 68 (1975), p. 137. See also D. Ostrogorsky and E. Stein, "Die Krönungsordnungen des Zeremonienbuches. Chronologische und verfassungsgeschichtliche Bemerkungen", Byz 7 (1932), pp. 226ff. for the evidence of a ceremony of proclamation of a Kaisar in AD 832 in Const. Porph., De Cer. I 43 (Reiske, 222-225). See also Konstantinos 259 and cf. Treadgold, "Problem", p. 333.
