He worked as a teacher at secondary education in high schools of Crete, Ileia and Athens.
He dealt with issues of aesthetics and philosophy in literature (especially the poetry of Angelos Sikelianos of which he was the main and most important connoisseur.
Dimopoulos was a personal friend of Sikelianos, apart from a keen scholar of his work, fact that gave a very personal/loving tone in his reviews and an 'insider' look at specific and difficult –always poetic- cases based in -very, possibly- private information.
His relationship with the work of Sikelianos had been a constant attempt (and care) of analysis, interpretation and explanation of the principles governing the work, the causes (also the "organic": the unbreakable unity of the human spirit and body of Sikelianos resulting in his idiosyncratic trends and moods) that created the specific aesthetic and worldviews of the poet, that created the forms and genres with which Sikelianos expressed himself (both in lyric, if such a discrimination is permitted, and also in dramatic poetry, the literary penetration and critic of Dimopoulos is crucial and valuable).
