The paper examines the possibility of interpreting the 2200 A band occurring in the interstellar extinction curve as being attributed to porous graphite. The results show that grains with radii smaller than 0.015 micron and a porosity degree in the range 0.02-0.25 are able to fit satisfactorily the peak at 4.6/micron and the band shape between 4 and 5.2/micron. Consideration of the expected density for such particles seems to confirm that interstellar grains may be porous but, at the same time, suggests that care must be taken when data concerning dust in the solar system are extrapolated to interstellar space.
